New electron donors for organic metals: the synthesis of highly conjugated bis-(1,3-dithiole) derivatives
Abstract
Routes to bis-(1,3-dithiole) derivatives with extended conjugation between the two heterocyclic rings are described. Compound (17) has been prepared in three steps from benzene-1,2-dithiol. Compounds (27) and (30), both prepared from 2,6-bis(bromomethyl)naphthalene, could not be isolated, but have been characterised as salts or complexes.
